GREPI EA 2938, Laboratoire d Enzymologie, Centre Hospitalier Universitaire, Grenoble, France
J Infect Dis 188:1593-604. 2003..It was concluded that the O(2)(-) production in the neutrophils of these patients was not sufficient to protect them against infections, and this X91(-) CGD phenotype must be considered to be a severe clinical form of CGD...

GREPI EA 2938 UJF, Laboratoire d Enzymologie, CHU 38043 Grenoble Cedex 9, France
Biochim Biophys Acta 1586:316-30. 2002..We concluded that residues 303 and 304 are crucial for the stable assembly of the NADPH oxidase complex and for electron transfer, but not for its proton channel activity...
